How can I make the newsletter signup form in the "Above footer widgets" to show up in one

Tryed the email newsletter plugin, but Mailchimps newsletter suted more for me. I would like to have a newsletter signup for above fotter on every page. That is why I put the embended code in a text widget.

Sadly it is showing in a list now and I would like to make it in a line next to each other.

Could you please help me solve this problem?

Thank you!
